Description

Technical Field

[0001] This invention relates to the field of film application equipment technology, and more specifically, to a super depth-of-field film application device and its application method. Background Technology

[0002] When manufacturing shell products, a film needs to be applied to the inside of the shell. Generally, shell products include an outer shell and an inner shell inserted into it. The inner shell and the outer shell are movable relative to each other, and the inner shell is longer than the outer shell. When applying the film, a circular film needs to be attached to the inner bottom surface of the inner shell. However, because the inner shell is relatively deep, during the film application process, on the one hand, the relative position of the inner shell and the outer shell is not fixed, making it difficult to control the stroke of the film application drive, resulting in problems such as excessive or insufficient clamping force. On the other hand, because the film is applied at a relatively deep depth, air bubbles are easily formed between the film material and the inner bottom surface of the inner shell during the internal film application process, resulting in poor film application quality. Summary of the Invention

[0003] This invention discloses a super depth-of-field film application device, which aims to improve the problems of poor film application quality and low efficiency of existing super depth-of-field film application devices.

[0004] The present invention adopts the following solution:

The feeding mechanism is adapted to provide a patch with a central hole to the film-applying mechanism; the film-applying mechanism includes a motion mechanism, a film-applying assembly, a first detection camera, and a second detection camera, wherein the motion mechanism is adapted to drive the film-applying assembly to pick up the patch from the film feeding mechanism and identify the position of the patch through the first detection camera; the second detection camera is disposed on the film-applying assembly and is configured to take pictures to identify the tube body position coordinates of the tube body assembly before film application, and match them with the identification results of the first detection camera to obtain the motion coordinates required for film application by the film-applying assembly, and apply the patch to the inner bottom surface of the tube body through the film-applying assembly; the detection mechanism is adapted to detect the concentricity of the patch and the tube body and transmit the detection results to the unloading mechanism; the unloading mechanism is adapted to unload qualified products and unqualified products separately according to the detection results of the detection mechanism.

[0006] Furthermore, the first shaping mechanism includes a first push rod assembly disposed below the clamping assembly; the clamping assembly is adapted to clamp the outer side of the shell of the shell assembly conveyed from the shell feeding mechanism, and the first push rod assembly includes a first push rod coaxially disposed with the tube body, the first push rod being adapted to rise after being clamped by the clamping assembly, so as to push the tube body with one end exposed at the bottom of the shell into the tube body to a preset depth;

[0007] The second shaping mechanism includes a flipping assembly and a second push rod assembly. The flipping assembly includes a lifting device and a flipping cylinder connected to the lifting device. The flipping cylinder is equipped with a clamping device to clamp the tube shell assembly from the side and flip it after being lifted to a predetermined height by the lifting device, so that the open end of the tube is facing down. Then, the lifting device lowers the tube shell assembly to fix it on the clamping assembly. The second push rod assembly is located below the turntable and includes a lifter and a top platform connected to the lifter. The top platform is shaped like a frustum to lift the tube body exposed from the shell upward to a fixed height under the drive of the lifter after the tube shell assembly is flipped, so as to ensure that the tube body height of each tube shell assembly after being aligned by the first shaping mechanism and the second shaping mechanism is the same.

[0008] Furthermore, the cleaning mechanism includes a purge air pipe disposed below the turntable, the purge air pipe being adapted to extend into the interior of the pipe body from below for purge.

[0009] Furthermore, a flipping mechanism is provided between the cleaning mechanism and the film-applying mechanism to flip the tube assembly so that the open end of the exposed tube faces upward.

[0010] Furthermore, the film application mechanism also includes a fixing and clamping assembly, which includes a moving mechanism and a tube clamping assembly. The tube clamping assembly is adapted to extend during the film application process of the film application assembly to clamp onto the tube body, so as to keep the tube body fixed at the corresponding height position.

[0011] Furthermore, the film application assembly includes a film suction rod, and the motion mechanism includes a lifting mechanism and a rotating mechanism. The lifting mechanism is disposed on the rotating mechanism, and the film suction rod is mounted on the lifting mechanism. The rotating mechanism is configured to drive the film suction rod to move between the film feeding mechanism and the turntable to pick up the film from the film feeding mechanism and attach it to the inside of the tube body of the tube assembly.

[0012] Furthermore, the end of the suction rod is provided with a suction head, which has a plurality of vacuum suction holes and an exhaust hole at the center. The exhaust hole is connected to a plurality of vent holes. The vacuum suction holes are suitable for adsorbing the patch. The exhaust hole corresponds to the center hole on the patch to provide an exhaust channel between the patch and the bottom surface of the tube during the film application process.

[0013] Furthermore, the film-applying mechanism also includes a clamping mechanism disposed below the turntable, which is adapted to clamp the lower end of the tube body during film application to prevent the suction rod from causing the tube body to move downward.

[0014] Furthermore, the feeding mechanism includes a first feeding component and a second feeding component. The first feeding component is adapted to convey qualified tube shell components to the next process; the second feeding component is configured to discharge unqualified products to a designated position.

[0015] The present invention also provides a method for applying a super depth-of-field film, using the super depth-of-field film application equipment described above, the steps of which are as follows:

[0016] S1. The tube and shell assembly is loaded and the first shaping and alignment are performed so that the non-open end of the tube is retracted into the shell.

[0017] S2. The turntable rotates one station to bring the tube shell assembly to the station of the second shaping mechanism; the tube shell assembly is flipped 180° by the flipping assembly so that the open end of the tube is facing down; then the second push rod assembly is driven to rise to a fixed height so that the tube body reaches the preset height position relative to the shell.

[0018] S3. The turntable continues to rotate one station to the station of the cleaning mechanism. The cleaning mechanism's blowing air pipe rises to enter the pipe body for blowing and dust removal.

[0019] S4. The turntable continues to rotate to reach the working position of the flipping mechanism, and the tube shell assembly is flipped again by the flipping mechanism so that the opening of the tube is facing upward.

[0020] S5. The turntable continues to rotate so that the tube assembly moves to the station of the film application mechanism. The film application structure picks up the patch with a through hole in the middle from the film feeding mechanism, and detects the position of the patch and the opening position of the tube body by two vision inspection mechanisms respectively. The control system identifies and corrects the patch to obtain the precise coordinates of the film application, and then the patch is attached to the inner bottom surface of the tube body.

[0021] S6. After the patch is placed, the turntable continues to rotate so that the tube assembly moves to the work station of the inspection mechanism. The inspection mechanism judges the concentricity of the patch and the tube body through visual inspection.

[0022] S7. After the inspection is completed, the turntable continues to rotate so that the tube shell assembly moves to the work station of the unloading mechanism. According to the inspection results of the inspection mechanism, the tube shell assemblies that meet the concentricity requirements and the tube shell assemblies that do not meet the requirements are unloaded to different positions respectively.

[0023] Beneficial effects:

[0024] This solution incorporates a tube / shell feeding mechanism, a first shaping mechanism, a second shaping mechanism, a cleaning mechanism, a film feeding mechanism, a film application mechanism, a detection mechanism, and a unloading mechanism on a turntable. The turntable's rotation allows for the transmission of the tube / shell assembly between various stations. The two shaping actions of the first and second shaping mechanisms ensure that the relative height between the tube and shell of each shaped assembly is identical, guaranteeing consistent film application height and improving application quality. Simultaneously, the film application mechanism determines the application coordinates by simultaneously detecting the film and tube positions, ensuring application accuracy. This solution guarantees both application quality and efficiency even in ultra-depth-of-field conditions. Attached Figure Description

Detailed Implementation

[0034] Example 1

[0035] Combination Figures 1 to 8As shown, this embodiment provides a super depth-of-field film application device, including: a turntable 1, and a tube housing feeding mechanism 3, a first shaping mechanism 4, a second shaping mechanism 5, a cleaning mechanism 6, a film material feeding mechanism 12, a film application mechanism 7, a detection mechanism 8, and a unloading mechanism 9 arranged along the circumference of the turntable 1; wherein, the turntable 1 is provided with a plurality of clamping components 2 for fixing the tube housing components 10; the turntable 1 is adapted to rotate so that the tube housing components 10 sequentially pass through the tube housing feeding mechanism 3, the first shaping mechanism 4, the second shaping mechanism 5, the cleaning mechanism 6, the film material feeding mechanism 12, the film application mechanism 7, the detection mechanism 8, and the unloading mechanism 9. Mechanism 5, cleaning mechanism 6, film application mechanism 7, testing mechanism 8, and unloading mechanism 9; the tube shell loading mechanism 3 is adapted to transport the fitted tube shell assembly 10 to the first shaping mechanism 4; the first shaping mechanism 4 and the second shaping mechanism 5 are configured to calibrate each tube shell assembly 10 to adjust the depth to which the tube body 1001 of each tube shell assembly 10 is inserted into the corresponding shell 1002; the cleaning mechanism 6 is adapted to blow air to clean the inside of the calibrated tube body 1001 to remove dust from the tube body 1001; The film feeding mechanism 12 includes a feeder to provide a patch with a central hole to the film application mechanism 7; the film application mechanism 7 includes a motion mechanism 71, a film application assembly 72, a first detection camera 73, and a second detection camera 74, wherein the motion mechanism 71 is adapted to drive the film application assembly 72 to pick up the patch from the film feeding mechanism 12, and the first detection camera 73 identifies the position of the patch on the film application assembly 72; the second detection camera 74 is disposed on the film application assembly and is configured to perform film application... The front camera identifies the position of the tube body 1001 of the tube shell assembly 10 and matches it with the result identified by the first detection camera 73 to obtain the motion coordinates of the film application assembly 72. The film application assembly 72 then applies the patch to the inner bottom surface of the tube body 1001. The detection mechanism 8 is adapted to detect the concentricity of the patch and the tube body 1001 and transmit the detection result to the unloading mechanism 9. The unloading mechanism 9 is adapted to unload qualified products and unqualified products separately according to the detection result of the detection mechanism 8.

[0036] Combination Figures 6 to 7As shown, in this embodiment, a rotating device is provided below the turntable 1 to drive the turntable 1 to rotate. The rotating mechanism 712 can be a stepper motor to ensure that the angle of rotation is the same each time. Multiple clamping components 2 are evenly distributed along the circumference on the turntable 1. Each clamping component 2 includes a V-shaped clamping plate 21 and a V-shaped clamping block 22. The rear end of the V-shaped clamping plate 21 is provided with an elastic element 23, and the V-shaped clamping plate 21 is adapted to slide on the track on the turntable 1, so that the V-shaped clamping plate 21 has elastic movement space, preventing excessive clamping force during clamping from damaging the tube shell assembly 10. The V-shaped clamping block 22 is connected to a clamping cylinder 24, which is adapted to push the V-shaped block towards the V-shaped clamping plate 21 to clamp it onto the shell 1002 of the cylindrical tube shell assembly 10. The tube assembly 10 includes a shell 1002 and a tube 1001. The shell 1002 is sleeved on the tube 1001 and can slide relative to the shell 1002.

[0037] Combination Figures 1 to 4 As shown, a transport robot 31 can be provided between the first shaping mechanism 4 and the tube loading mechanism 3. The transport robot 31 transports the tube assembly 10 from the tube loading mechanism 3 to the clamping assembly 2 located at the first shaping mechanism 4. The first shaping mechanism 4 includes a first push rod 41 assembly disposed below the clamping assembly 2. The clamping assembly 2 is adapted to clamp the outer side of the shell 1002 of the tube assembly 10 transferred from the tube loading mechanism 3. The first push rod 41 assembly includes a first push rod 41 coaxially disposed with the tube body 1001. The first push rod 41 is adapted to be lifted by a lifting device after being clamped by the clamping assembly 2, so as to push the tube body 1001 with one end exposed at the bottom of the shell 1002 into the tube body 1001 to a preset depth. Here, the tube assemblies 10 are already neatly arranged on the tube loading mechanism 3, and the open end of the tube body 1001 is facing upward. The purpose of the first shaping mechanism is to push the portion of the non-open end of the tube 1001 that is exposed inside the housing 1002 into the housing 1002. The tube assembly 10, whose non-open end of the tube 1001 is already inside the housing 1002 in its initial state, remains unaffected. The diameter of the first push rod 41 is smaller than the diameter of the through hole in the housing 1002, allowing the first push rod 41 to extend into the housing 1002 to push the tube 1001 into the housing 1002.

[0038] The second shaping mechanism 5 includes a flipping assembly 51 and a second push rod assembly 54. The flipping assembly 51 includes a lifting device 53 and a flipping cylinder connected to the lifting device 53. The flipping cylinder is equipped with a clamping device 52 to clamp the shell assembly 10 from the side and flip it after being lifted to a predetermined height by the lifting device 53, so that the open end of the tube body 1001 faces downward. Then, the lifting device 53 lowers the tube body assembly 10 to fix it on the clamping assembly 2. The second push rod assembly 54 is located below the turntable 1. It includes a lifter 542 and a top platform 543 connected to the lifter 542. The top platform 543 is shaped like a frustum to lift the tube body 1001 exposed from the shell 1002 upward to a fixed height under the drive of the lifter 542 after the shell assembly 10 is flipped, so as to ensure that the height of the tube body 1001 of each shell assembly 10 after being aligned by the first shaping mechanism 4 and the second shaping mechanism 5 is the same. Here, the tube shell assembly 10 can be rotated 180° by the flipping component 51, so that the opening of the tube body 1001 faces downward, and the portion of the tube body 1001 exposed in the shell 1002 faces downward. After flipping, part of the tube body 1001 can pass through the through hole on the turntable 1 and be located below the turntable 1, where the clamping component 2 clamps the portion of the shell 1002. The second push rod assembly 54 is provided with a second push rod 541, which connects the lifting device 542 and the top platform 543. During shaping and positioning, the top platform 543 is located at a certain height below the tube body 1001. At this time, the diameter of the through hole on the turntable 1 for the tube body 1001 is smaller than the diameter of the shell 1002. Therefore, when the tube shell assembly 10 is placed on the turntable 1, it can be positioned by the bottom surface of the shell 1002 to ensure that the height position of the shell 1002 is fixed each time it is shaped and positioned. During shaping, the top platform 543 rises to a fixed height under the control of the lifting device 542 to push the tube 1001 upwards, so that the tube 1001 and the shell 1002 reach a preset relative height, resulting in a certain height difference or flushness between the non-open end of the tube 1001 and the top surface of the shell 1002. Since the height of the top platform 543 is fixed each time, it can be ensured that the relative height position of the tube 1001 and the shell 1002 on each tube-shell assembly 10 is the same.

[0039] Combination Figure 5As shown, the cleaning mechanism 6 includes a purge air pipe 61 disposed below the turntable 1. The purge air pipe 61 is adapted to extend into the tube body 1001 from below for purge. A lifting structure 62 can be provided below the purge air pipe 61 to drive it into the tube body 1001 for purge. The purge air pipe 61 is positioned directly below the through hole on the turntable 1, allowing it to extend into the tube body 1001 without prior alignment. A flipping mechanism 11 is provided between the cleaning mechanism 6 and the film-applying mechanism 7 to flip the tube shell assembly 10 so that the open end of the tube body 1001 faces upwards. This flipping mechanism can have the same structure as the flipping assembly 51.

[0040] The film feeding mechanism 12 includes an existing feeder to provide patches with a central hole to the laminating mechanism 7. Here, the through hole can be formed in the center of the patch during patch production, or a punching mechanism can be installed on the film feeding mechanism 12 to punch the hole first during feeding, and then the laminating mechanism 7 picks up the patch with the central hole and places it at the laminating station for lamination. The patch is an insulating sheet.

[0041] Combination Figures 1 to 8As shown, the film application mechanism 7 includes a motion mechanism 71, a film application assembly 72, a first detection camera 73, and a second detection camera 74. The motion mechanism 71 is adapted to drive the film application assembly 72 to pick up the film from the film feeding mechanism 12, and the first detection camera 73 identifies the position of the film on the film application assembly 72. The second detection camera 74 is disposed on the film assembly and is configured to take pictures to identify the position of the tube body 1001 of the tube shell assembly 10 before film application, and match the identification result with the first detection camera 73 to obtain the motion coordinates of the film application assembly 72, and then attach the film to the inner bottom surface of the tube body 1001 through the film application assembly 72. It also includes a fixing clamping assembly 75, which includes a moving mechanism and a tube clamping assembly. The tube clamping assembly is adapted to extend during the film application process of the film application assembly 72 to clamp the tube body 1001 to keep the tube body 1001 fixed at a corresponding height position. The motion mechanism 71 described herein includes a four-axis motion mechanism 71, which includes a lifting mechanism 711, a rotating mechanism 712, and an XY axis moving mechanism. The film application assembly includes a film suction rod 721. The lifting mechanism 711 is disposed on the rotating mechanism 712, and the film suction rod 721 is mounted on the lifting mechanism 711. The rotating mechanism 712 is configured to drive the film suction rod 721 to move between the film feeding mechanism 12 and the turntable 1, so as to pick up the film from the film feeding mechanism 12 and attach it to the inside of the tube body 1001 of the tube shell assembly 10. Here, a suction head 722 is provided at the end of the suction rod 721. The suction head 722 is provided with a plurality of vacuum suction holes 7221 and an exhaust hole 7222 at the center position. The exhaust hole 7222 is connected to a plurality of vent holes 7223. The vacuum suction holes 7221 are suitable for adsorbing the patch. The exhaust hole 7222 corresponds to the center hole on the patch to provide an exhaust channel between the patch and the inner bottom surface of the tube 1001 during the film application process. During film application, the patch automatically adheres to the inner bottom surface of the tube 1001, and the air between the patch and the inner bottom surface of the tube 1001 is discharged through the center hole and the exhaust hole 7222, and then discharged into the atmosphere through the vent holes 7223. This setting can effectively prevent the problem of air bubbles in the film application caused by the difficulty in venting internal gas in ultra-depth-of-field environments.

[0042] In a preferred embodiment, the film-applying mechanism 7 further includes a clamping mechanism 76 disposed below the turntable 1. The clamping mechanism 76 is adapted to clamp against the lower end of the tube 1001 during film application to prevent the suction rod 721 from causing the tube 1001 to move downward. By cooperating with the fixing clamping assembly 75, the clamping mechanism 76 acts on the tube 1001, preventing the downward pressure during film application from causing changes in the relative position of the tube 1001 and the housing 1002, and also preventing the tube 1001 from shaking during film application, thereby improving the quality of film application.

[0043] The detection mechanism 8 includes a visual detection device, which can be used to detect the concentricity of the tube body 1001 and the patch. The visual detection mechanism 8 takes a picture of the attached tube shell assembly 10 to obtain the outline of the tube body 1001 and the outline of the patch, thereby analyzing the deviation value of the center position of the two, and judging the concentricity through the deviation value.

[0044] In this embodiment, the unloading mechanism 9 includes a first unloading component 91 and a second unloading component 92. The first unloading component 91 is adapted to transport qualified tube shell components 10 to the next process; the second unloading component 92 is configured to unload unqualified products to a designated location for discharge. The unloading mechanism 9 may include an unloading robot and an unloading production line. The unloading robot is used to place qualified and unqualified tube shell components 10 onto two different unloading production lines according to the detection results of the detection mechanism 8.

[0045] The solution in this embodiment achieves automated film application under ultra-depth-of-field conditions, with good film application quality and high efficiency.

[0046] Example 2

[0047] The present invention also provides a method for applying a super depth-of-field film, using the super depth-of-field film application equipment described above, the steps of which are as follows:

[0048] S1. The tube and shell assembly 10 is loaded and the first shaping and positioning is performed so that the non-open end of the tube 1001 is retracted into the shell 1002.

[0049] S2. The turntable 1 rotates one station to bring the tube shell assembly 10 to the station of the second shaping mechanism 5; the tube shell assembly 10 is rotated 180° by the flipping assembly 51 so that the open end of the tube body 1001 faces downward; then the second push rod assembly 54 is driven to rise to a fixed height so that the tube body 1001 reaches a preset height position relative to the shell 1002.

[0050] S3. Turntable 1 continues to rotate one station to the station of cleaning mechanism 6. The blowing air pipe 61 of cleaning mechanism 6 rises to enter the pipe body 1001 for blowing and dust removal.

[0051] S4. Turntable 1 continues to rotate to reach the working position of the flipping mechanism, and the tube shell assembly 10 is flipped again by the flipping mechanism so that the opening of the tube body 1001 faces upward.

[0052] S5. Turntable 1 continues to rotate so that the tube shell assembly 10 moves to the station of the film application mechanism 7. The film application structure picks up the patch with a through hole in the middle from the film feeding mechanism 12, and detects the position of the patch and the opening position of the tube body 1001 respectively through two vision detection mechanisms 8. The control system identifies and corrects to obtain the precise coordinates of the film application, and then the patch is attached to the inner bottom surface of the tube body 1001.

[0053] S6. After the patch is applied, the turntable 1 continues to rotate so that the tube housing assembly 10 moves to the work station of the inspection mechanism 8. The inspection mechanism 8 judges the concentricity of the patch and the tube body 1001 by visual inspection.

[0054] S7. After the inspection is completed, the turntable 1 continues to rotate so that the shell assembly 10 moves to the station of the unloading mechanism 9. According to the inspection results of the inspection mechanism 8, the shell assembly 10 that meets the concentricity requirements and the shell assembly 10 that does not meet the requirements are unloaded to different positions respectively.

[0055] In this process, each tube and shell assembly 10 is first shaped twice by the first shaping mechanism 4 and the second shaping mechanism 5 to ensure that the relative height of the tube body 1001 and the shell 1002 of each shaped and aligned tube and shell assembly 10 is the same, thus ensuring that the film application depth is the same. In addition, during the film application process, the accuracy of the obtained film application coordinates can be improved by identifying and aligning the tube body 1001 and the patch respectively, thereby improving the accuracy of the film application. By setting a central hole on the patch for venting during the film application process, the generation of air bubbles can be effectively reduced.

[0056] This embodiment enables film application at locations with ultra-deep focus, solves the problem of air bubbles in the film, and improves the quality of the film application.

[0057] It should be understood that the above are merely preferred embodiments of the present invention, and the scope of protection of the present invention is not limited to the above embodiments. All technical solutions that fall within the scope of the present invention are within the scope of protection of the present invention.

10. A method for applying a super depth-of-field film, characterized in that, The steps of using the ultra-depth-of-field film application device according to any one of claims 1-9 are as follows: S1. The tube and shell assembly is loaded and the first shaping and alignment are performed so that the non-open end of the tube is retracted into the shell. S2. The turntable rotates one station to bring the tube shell assembly to the station of the second shaping mechanism; the tube shell assembly is flipped 180° by the flipping assembly so that the open end of the tube is facing down; then the second push rod assembly is driven to rise to a fixed height so that the tube body reaches the preset height position relative to the shell. S3. The turntable continues to rotate one station to the station of the cleaning mechanism. The cleaning mechanism's blowing air pipe rises to enter the pipe body for blowing and dust removal. S4. The turntable continues to rotate to reach the working position of the flipping mechanism, and the tube shell assembly is flipped again by the flipping mechanism so that the opening of the tube is facing upward. S5. The turntable continues to rotate so that the tube assembly moves to the station of the film application mechanism. The film application structure picks up the patch with a through hole in the middle from the film feeding mechanism, and detects the position of the patch and the opening position of the tube body by two vision inspection mechanisms respectively. The control system identifies and corrects the patch to obtain the precise coordinates of the film application, and then the patch is attached to the inner bottom surface of the tube body. S6. After the patch is placed, the turntable continues to rotate so that the tube assembly moves to the work station of the inspection mechanism. The inspection mechanism judges the concentricity of the patch and the tube body through visual inspection. S7. After the inspection is completed, the turntable continues to rotate so that the tube shell assembly moves to the work station of the unloading mechanism. According to the inspection results of the inspection mechanism, the tube shell assemblies that meet the concentricity requirements and the tube shell assemblies that do not meet the requirements are unloaded to different positions respectively.
